International Journal of Systematic and Evolutionary Microbiology publishes papers dealing with all phases of the systematics of prokaryotes, yeasts and microfungi, protozoa and microalgae, including taxonomy, nomenclature, identification, phylogeny, evolution, biodiversity, characterization and culture preservation. Its scope covers phylogenetic and evolutionary aspects of all micro-organisms. International Journal of Systematic and Evolutionary Microbiology will publish molecular environmental papers that have a strong taxonomic or evolutionary content.
The journal does not encourage the submission of results of intraspecific characterization, e.g. typing methods such as rrn operon sequence microheterogeneities, nor the development of identification systems based upon these results to be used for diagnostic purposes. Infrasubspecific taxa are not covered by Rules of the International Code of Nomenclature of Bacteria and papers on such taxa, e.g. of epidemiological interest, are outside the scope of the journal; authors should consider a more general journal such as Microbiology.
It is not a conflict of interest to be an Editor as well as an author, as long as the Editor is not involved in any component of the peer review process.
- Descriptions of the majority of all new prokaryotic and yeast species
- Validation Lists - to validate officially the publication of names of prokaryotes not published in the IJSB/IJSEM
- Opinions of the Judicial Commission of the International Committee on Systematics of Prokaryotes (ICSP)
- Minutes of ICSP subcommittees
The Note will be considered to be the usual format for papers; however, Note papers are not identified as such in the journal. The Editors will insist that papers be shortened to the Note format where appropriate. Notes are reviewed to the same standard as full papers and are not considered to be preliminary communications.
A paper by Kämpfer et al.(2003) outlining a standardized format for the description of a novel species of an established genus is freely available at International Journal of Systematic and Evolutionary Microbiology online; authors are encouraged to follow this model where possible.
Reviews should be brief summaries of developments in fast-moving areas. They must be based on published articles; they may address any subject within the scope of International Journal of Systematic and Evolutionary Microbiology. Reviews may be solicited or unsolicited. All Reviews are immediately accessible upon publication.
4.3 Letters to the Editor
Critiques of taxonomic papers, when done in good taste, will be considered for publication. Letters to the Editor must include data to support the writer's argument and are intended only for comments on articles published previously in the journal, the authors of which will be invited to respond.
4.4 Designation of naotype strains
A neotype strain is a strain that replaces, by international agreement, a type strain which is no longer in existence. The neotype should possess the characteristics given in the original description; any deviations should be explained. A proposal of a neotype strain must be published in the Journal together with a reference (or references) to the first description and name for the micro-organism, a description (or reference to a description) of the proposed neotype strain, and a record of the author's designation for the neotype strain and of at least two culture collections in different countries from which cultures of the strain are available. The neotype strain becomes established 2 years after the date of its publication in the Journal, provided that there are no objections, which must be referred within the first year of the publication of the neotype to the Judicial Commission for consideration. A neotype strain should be proposed only after a careful search has shown that none of the strains on which the original description was based is extant. If an original strain is subsequently discovered, the matter should be referred immediately to the Judicial Commission.
Send items relating to the International Committee on Systematics of Prokaryotes (ICSP) in the same way as normal online submissions.
4.5 Taxonomic Notes
This section permits the presentation of material or proposals in advance of formal discussion at a meeting of the ICSP so that there may be international awareness of the item. Notes may also transmit, in concise form, items of importance to systematics arising from publications other than the International Journal of Systematic and Evolutionary Microbiology, from the ICSP, or from individual scientists.
4.6 Requests for an Opinion
When strict adherence to the Rules of bacteriological nomenclature would only produce chaos or would not result in nomenclatural stability, exceptions to the Rules may be requested of the Judicial Commission of the ICSP. 'Requests for an Opinion' must be accompanied by a fully documented statement of the relevant facts. When challenging a Request for an Opinion, authors must state the basis of the challenge and support it by a documented statement of the relevant facts. If an Opinion is requested in the text, 'Request for an Opinion' should appear in the title. Note that straightforward differences in taxonomic opinion are not generally considered as Requests for an Opinion.
4.8 Minutes of International Committee on Systematics of Prokaryotes
Guidelines on the preparation of taxanomic subcommittee minutes are available here.
4.9 Notification lists
Notifications lists are complied by the Journal: notification of new names of prokaryotes, new combinations, and new taxonomic opinions that have been published in the International Journal of Systematic and Evolutionary Microbiology.
4.10 Validation lists
Validation lists are compiled by the Journal. As required by the Bacteriological Code, the International Journal of Systematic and Evolutionary Microbiology publishes Validation Lists containing new names that were effectively published in other journals. For validation of new names published elsewhere, authors should submit a covering letter and two reprints or photocopies or a PDF file of the published article(s) to the Editorial Office. The requirements for validation are identical to those for publication in International Journal of Systematic and Evolutionary Microbiology; i.e. authors must provide evidence that types are deposited in two recognised culture collections in two different countries.
4.11 List of changes in taxonomic opinion
Lists of changes in taxonomic opinion are compiled by the Journal. These result from the creation of synonyms or emended descriptions to be made widely available to the public. The names that are to be used are those that are the ‘correct names’ (in the sense of Principle 6) in the opinion of the bacteriologist, with a given circumscription, position and rank. A particular name, circumscription, position and rank does not have to be adopted in all circumstances. Consequently, the List of Changes in Taxonomic Opinion must be considered as a service to bacteriology and it has no ‘official character’, other than providing a centralized point for registering/indexing such changes in a way that makes them easily accessible to the scientific community.
Taxonomic opinions included in the List cannot be considered as validly published nor, in any other way, approved by the International Committee on Systematics of Prokaryotes and its Judicial Commission.
Scientists wishing to have changes in taxonomic opinion included in future lists should send one copy of the pertinent reprint or a photocopy or a PDF file thereof to the International Journal of Systematic and Evolutionary Microbiology Editorial Office or to the Lists Editor. It must be stressed that the date of proposed taxonomic changes is the date of the original publication not the date of publication of the list.

5. Publication of new taxa
For all papers reporting novel taxa, please refer to our nomenclature guidelines.
5.1 Publication of new taxon
For a description of a new taxon, the following must be included with the submitted paper:
- A list of the strains included in the taxon.
- A statement or tabulation of the characteristics of each strain (see Presentation of strain data).
- A list of characteristics considered essential for membership in the taxon.
- A list of characteristics which qualify the taxon for membership in the next higher taxon.
- A list of diagnostic characteristics, i.e. characters which distinguish the taxon from closely related taxa.
- Designation of the type for that taxon.
- The reactions of the type strain of a new species.
- For all characteristics that vary among strains within the species; e.g. if 80% of the strains ferment trehalose, the specific reaction of the type strain must be defined.
Suitable photomicrographs and, if necessary, electron micrographs may be used as part of the description to show any morphological or anatomical characters that may be pertinent to its classification. See Photographs.
5.2 Valid publication of names of bacterial taxa
Please refer to the International Code of Nomenclature of Bacteria.
The Principles and Rules of nomenclature are published in the International Code of Nomenclature of Bacteria (1990 Revision). International Code of Nomenclature of Bacteria (Washington, DC: American Society for Microbiology), now renamed as the International Code of Nomenclature of Prokaryotes. Alterations to the Code published since 1990 can be found online at http://www.bacterio.net. In summary, the requirements for the valid publication of new names and combinations are as follows:
- The new name or combination must be published in the International Journal of Systematic and Evolutionary Microbiology. If published elsewhere, the new name or combination is not validly published until it is published in the International Journal of Systematic and Evolutionary Microbiology. The date of publication of the new name or combination is the date of publication in the International Journal of Systematic and Evolutionary Microbiology.
- New names must be formed in accordance with the rules of the Code. Guidelines for the formation of correct names can be found in Appendix 9: Orthography to the International Code of Nomenclature of Prokaryotes (H.G. Trüper & J.P. Euzéby, Int. J. Syst. Evol. Microbiol.59, 2107-2113, 2009) (doi: 10.1099/ijs.0.016741-0); How to name a prokaryote? Etymological considerations, proposals and practical advice in prokaryote nomenclature (H.G. Trüper, FEMS Microbiol. Rev.23, 231-249, 1999) and How to name new taxa of prokaryotes? (A. Oren, Taxonomy of Prokaryotes - Methods in Microbiology 38, 438-463. Edited by F. A. Rainey and A. Oren. Amsterdam: Elsevier/Academic Press, 2012). Assistance with names is often required of those with competence in Latin and Greek. Authors are encouraged to contact one of the journal's nomenclature reviewers: Bernhard Schink (email@example.com), Aharon Oren (firstname.lastname@example.org) or George Garrity (email@example.com) for guidance prior to the submission of their manuscripts.
- The name should be clearly proposed as a new name or combination. New names are ordinarily proposed by an author appending the phrase 'species nova' (abbreviation: sp. nov.), 'genus novum' (abbreviation: gen. nov.), 'nomen novum' (abbreviation: nom. nov.), 'combinatio nova' (abbreviation: comb. nov.), or the like after the name or combination being proposed as new.
- The nomenclature of prokaryotes is not independent of virological, botanical and zoological nomenclature. When naming new taxa in the rank of genus or higher, due consideration is to be given to avoiding names which are regulated by the International Code of Virus Classification and Nomenclature, the International Code of Nomenclature for algae, fungi and plants and the International Code of Zoological Nomenclature. Excellent listings of names can be found online at Species 2000 and in the online databases given below, and also in the following books. Algae: De Toni, J. B. (1889) Sylloge Algarum; Index Kewensis, 1895–present, London: Royal Botanic Gardens. Bacteria: see Nomenclature of bacteria. Fungi: Clements, F. E. & Shear, C. L. (1931), The Genera of Fungi, New York: H. W. Wilson; Saccardo, P. A. (1882–1921) Sylloge Fungorum, Pavia, 25 vol.; Index to Fungi (1940–present), Kew: Commonwealth Mycological Institute. Yeasts: see Nomenclature of unicellular eukaryotes. Protozoa: Index Zoologicus (1902–present), London: Zoological Society. Plants: Index Nominum Genericorum. Animals: Nomenclator Zoologicus.
- The taxon must be accompanied by a description or by a reference to a previously published description of the taxon.
- The nomenclatural type of the taxon must be designated. For species and subspecies, the type strain should be described and designated by the author's strain number as well as by the strain numbers under which it is held by at least two culture collections in TWO different countries from which the strain is available. For new combinations, the type strain must be cited. Culture Collections that are members of the World Federation of Culture Collections generally qualify (for a list see here. In cases of doubt the editors may be consulted.
According to the Rule 27(2)b, the derivation (etymology) of a new name (and if necessary of a new combination) must be given - see a recent issue of International Journal of Systematic and Evolutionary Microbiology.
5.3 Publication of names of unicellular eukaryotes
Please refer to the International Code of Nomenclature for algae, fungi and plants or to the International Code of Zoological Nomenclature, as applicable. Much of what is written above for bacteria is relevant to the description of new taxa of unicellular eukaryotes. In the case of fungi and microfungi, according to the rules of the International Code of Nomenclature for algae, fungi and plants, a Latin diagnosis of the new taxon may be included, but is no longer compulsory, and the journal requires that an etymology/description in English in a style similar to that for prokaryotes be given.
